Includes also non-TIMAS Data: UT, altitude, invariant latitude, L shell, magnetic local time, geomagnetic latitude (signed - n/s hemisphere), average magnetic field vector in GSM coordinates at Polar (uses KH's co-ord conversion code), spacecraft potential from EFI data base, solar zenith angles at each end of the field line, time delayed solar wind parameters from WIND (Using KH's database) interpolated across data gaps of less than 10 minutes, IMF in GSM, solar wind dynamic pressure (nPa), solar wind density (/cc), solar wind velocity (km/sec). This is a summary data base.It does not contain detailed energy step and pitch angle information for each data point. Extends over all altitudes, invariant latitudes and MLT. Below altitude of 4.0 Re 2 spin resolution (12s), above altitude of 4.0 Re 4 spin resolution (24s). Reference:E.G.

In particular background subtraction, short averaging intervals and the normally low count rates for minor ions (O+, He+, and He++) lead to many data intervals where the data values reported are not statistically significant. The data files therefore contain many diagnostic parameters and data quality flags.
